Laboratory experience is vital to undergraduate science education. It allows students to observe and conduct engaging experiments to enhance their skills and literacy, helps them retain knowledge, and deepens their understanding of related content covered in lectures. This paper reports a 4-week undergraduate laboratory exercise on…

Colloidal stability is one of the most important criteria in the application strategy of colloidal nanoparticles in the continuous phase. The branches include ecology, involving coagulation as a purification method; medicine as nanocarriers; biology as blood coagulation, etc. A chemist versed in these concepts is a high-performing chemist in…

The use of a multicompartment electrochemical cell for the potentiometric determination of solubility product constants of aqueous I[superscript -], Br[superscript -], SCN[superscript -], and Cl[superscript -] salts of silver is presented. An electrochemical cell presented in this study contained multiple half-cells made of disposable drinking…

The implementation of a laboratory exercise in an undergraduate chemistry course, where students perform a comparison of three different synthetic methods toward [Cu(Cl)(IPr)]-complexes (IPr = N,N'-bis(2,6-diisopropylphenyl)imidazol-2-ylidene), is described. The students are introduced to the continuous improvement of reactions in terms of green…

Plant extracts and their components have been reported to have antimicrobial properties against phytopathogens. Although such properties could be harnessed for the development of new pathogen control strategies, there are no standardised methods for their assessment in different extracts. The laboratory exercise presented here involves the use of…

An organic chemistry experiment designed for senior undergraduates focuses on bifunctional catalysis, a critical yet often omitted topic at the undergraduate level, but essential for advanced studies in chemistry. By utilization of a tertiary amine-thiourea catalyst in the asymmetric Michael addition reaction, the experiment showcases the…

Liquid metals are widely applied in various fields, including chemistry, catalysis, energy storage, chemical sensing, and stretchable electronics, due to their unique deformabilities. However, their behavior under a rod or ring electrode has never been analyzed. Furthermore, research on the deformation behavior of eutectic Ga--In (EGaIn), the most…

The COVID-19 pandemic was an unprecedented event that, out of necessity, drastically changed the way undergraduate chemistry courses were taught. With the cancellation of in-person classes, laboratory experiences were delayed and/or moved to the virtual space, the latter keeping the general framework of the laboratory experiment but removing the…

Ferrocene is an organometallic compound widely incorporated into undergraduate organic and inorganic chemistry curricula. Traditional laboratory experiments typically involve the Friedel-Crafts acylation of ferrocene to produce acetylferrocene or diacetylferrocene, with a purification method focused on column chromatography. To expand the…

A renewed experimental procedure for the unknown carbonyl experiment has been developed using hydrazone synthesis, thin layer chromatography (TLC) analysis, and melting point determination to differentiate between structurally similar ketones and aldehydes in undergraduate organic chemistry practical courses. Benzaldehyde, p-tolualdehyde,…

Herein, we present an integrated upper division chemistry laboratory experiment involving the synthesis, characterization, and evaluation of catalytic metal--organic frameworks (MOFs). Experiments are designed to facilitate the solvothermal synthesis and characterize MOFs, including UiO-66, UiO-66-NH[subscript 2], and UiO-66-NO[subscript 2]. The…

Normal phase thin layer chromatography is a widely taught technique in undergraduate organic chemistry laboratory courses. To understand how the technique works, students must have a strong conceptual understanding of polarity and intermolecular forces. Unfortunately, many students have misconceptions regarding how polarity and intermolecular…

Electrochemical characterization techniques are essential for studying and developing advanced materials across various fields, from corrosion science to energy storage, photovoltaics, and bioelectrochemistry. However, these techniques are often under-represented in educational curricula. This practical guide with a hands-on laboratory experiment…

A multicomponent reaction was adapted and successfully applied in the major organic course, which involves synthesizing and characterizing a 1,3-benzoxazine derived from paracetamol extracted from tablets of the worldwide well-known medicine Tylenol. Using paracetamol as a reagent is a motivational strategy in undergraduate laboratories to meet…

Wheat powdery mildew is an important fungal pathogen of wheat with an obligatory biotrophic lifestyle (a parasite that can only develop on a living host). We investigated the genetics of this host-pathogen interaction by using phenotyping and PCR assays to detect genes in both wheat and powdery mildew, which are known determinants of the outcome…
